카시니호의 통과를 기다리고 있는 엔켈라두스의 남극 지역을 촬영한 이 사진은 얼음 분출이 발생하고 있는 엔켈라두스의 남극을 가장 지근거리로 통과하기 위해 접근하는 카시니 호에 의해 촬영되었다.
구불구불한 경계를 이루고 있는 엔켈라두스의 남극지역이 아래 보이는데 이곳은 겨울의 어둠에 잠겨있는 상태이다.

 

이 사진은 96,000 킬로미터 지점에서 사진을 촬영한 다음 바로 촬영된 사진이다.

이 사진은 2015년 10월 28일  카시니 호에 장착된 협각 카메라를 이용하여 초록색 가시광선 파장으로 촬영되었다.

 

사진이 촬영될 당시 엔켈라두스와 카시니호의 거리는 61,000킬로미터였으며 태양-엔켈라두스-카시니 호가 42도 각도로 정렬해 있었다.

사진의 해상도는 픽셀당 365 미터이다.

PIA17203: Heading for the South Pole

Original Caption Released with Image:

The south polar region of Saturn's active, icy moon Enceladus awaits NASA's Cassini spacecraft in this view, acquired on approach to the mission's deepest-ever dive through the moon's plume of icy spray. The wavy boundary of the moon's south polar region is visible at bottom, where it disappears into wintry darkness.

This view was captured shortly after PIA17202.

This view looks towards the Saturn-facing side of Enceladus. North on Enceladus is up and rotated 22 degrees to the right. The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Oct. 28, 2015.

The view was acquired at a distance of approximately 38,000 miles (61,000 kilometers) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 42 degrees. Image scale is 1,198 feet (365 meters) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.
